The latest generations of interspecies grapevine hybrids are increasingly attracting the attention of producers, especially due to increased production safety and reduced use of pesticides. The economic effect is evident, and the obtained product follows modern world trends in the production of safe food. The aim of this paper is to examine the technological characteristics of three varieties of Morava, Johanniter and Riesling Rhine in the conditions of the Banja Luka region. Varieties Morava and Johanniter belong to the group of interspecies hybrids. The mentioned varieties were compared with the Riesling Rhine variety, which belongs to the varieties of the noble vine and represents the standard for the comparison of the given varieties. The focus of the research was on examining the yield of varieties, the characteristics of grapes and berries, as well as the quality of grapes. Elements of the mechanical composition of grapes and berries were made according to the method of Prostoserd (1946), and the characteristics of grape juice (% Brix, titratable acidity and pH value) according to official OIV methods. The variety Johanniter had the lowest weight of grapes (73.85 g), and the variety Morava had the highest weight (128.61 g). The varieties Johanniter and Riesling Rhine had a relatively high sugar content in grape juice (22.1%), while the variety Morava had a high sugar content (25.93%).
